SPlNDLE-DRIVING AND BAND-TENSION DEVICE FOR SPINNING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 665,265, dated January 1, 1901.

Application filed October 5, 1900. Serial No- 32.135. KNO model-l To all whom it may concern:

Be it known that I, JOSEPH E. PHILLIPS, a citizen of the United States, residing at Oarlisle, in the county of Cumberland and State of Pennsylvania, have invented a certain new and useful Spindle-Driving and Band-Tension Device for Spinning-Machines, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to spindle-driving and band-tension devices for spinning-machines, one object in viewbeing to provide a simple, efficient, and reliable driving device receiving its power from the main drivingshaft of the machine, which is located above the plane of the spindle-rails, the said driving device serving to simultaneously actuate spindles at opposite sides of the driving-shaft.

Another important object of the invention is to provide, in connection with a single endless driving-band, means for automatically exerting the requisite tension on the drivingband to insure its constant frictional driving engagement with the spindles and pulley on the driving-shaft.

Afurther object of the invention is to provide a means whereby the tension-pulley may be adjusted or tilted to any desired angle or inclination in order to enable the drivingband to run free at the several points where it crosses.

Other objects and advantages of the invention will appear in the course of the subjoined description.

The invention consists in spindle-driving and band-tension devices for spinning-machines embodying certain novel features and details of construction and arrangement of parts, as hereinafter fully described, illustrated in the drawings, and incorporated in the claims.

In the accompanying drawings, Figure 1 is a vertical cross-section through a sufficient portion of a spinning-machine frame to illustrate the application of the present improvements thereto. Fig. 2 is a detail vertical longitudinal section taken adjacent to one end of the machine in line with the driving-shaft. Fig. 3 is a detached perspective view of the driving-band, showing the manner of reeving the same around the several pulleys and spindles. Fig. 4 is a detail vertical section showing the manner of adjusting the tension-pulley bracket. Fig. 5 is a detail view showing a driving-cylinder for use in place of a shaft and pulleys.

Similar numerals of reference designate corresponding parts in all figures of the drawings.

Referring to the drawings, 1 designates the frame of a spinning-machine, which may be of the usual construction, in which the main driving-shaft 2 is located in a plane above the spindle-rails 3, 4 designating the spindles located at opposite sides of the machine and 5 indicating the band-receiving pulleys of the spindles, or, in other words, the spindle-pulleys.

In carrying out the present invention I employ a single endless driving-band 6 for a plurality of spindles 4. In order to actuate the driving-band 6, the shaft 2 is equipped with driving-pulleys 7, one of such pulleys being employed for each drivingband 6. Each pulley 7 is further provided with two peripheral grooves 8, in which different portions of the driving-band are received. The diameter of the pulley 7 is such that the lowest portion of its periphery is in the same horizontal plane with the band-receiving pulleys 5 of the spindles 4t, or substantially so, as clearly illustrated in Figs. 1 and 3. In this way the portion of the band traveling between the spindles is tangential, or substantially so, to the driving-pulley 7, thus enabling the band to run freely from or upon the driving-pulley.

Arranged beneath the driving-pulley 7 is a tension device, consisting of a pulley 9, peripherally grooved to receive the drivingband 6, and a bracket 10, which serves as a guide and housing for the tension-pulley. The bracket 10 comprises parallel upright portions or arms 11, united by a base or connecting portion 12, which receives a clamping and adjusting screw 13, passing through a slot 14 in a horizontal bar 15, forming part of the frame of the spinning-machine. The arms or portions 11 of the bracket 10 are terminally and longitudinally slotted, as shown at 16, to admit of the up-and-down play of the journals or trunnions 17, projecting laterally from opposite sides of the tension-pulley 9.

By the construction just above described the pulley 9 is hung freely in and suspended by the driving-hand 6, and the entire weight of the pulley 9 is utilized for exerting tension on the driving-band sufficient to insure the effective engagement of said band with the spindles and driving-pulley. As the driv-' ing-band stretches or lengthens the tension pulley 9 gravitates, the journals 17 being free to move downward in the slots 16 of the bracket 10. As the downwardlymoving portion of the band 6 rests in one of the grooves of the driving-pulley 7 and as the upwardlymoving portion of said band runs in the other groove of the driving-pulley, it is advisable, in order to secure reliability in operation, to set the tension-pulley slightly at an angle, as illustrated in Fig. 2, wherein it will be observed that the axis of the tension-pulley is not exactly parallel with the axis of the driving-shaft 2. By setting the tension-pulley at the proper angle one side of the tension-pulley may be brought into alinement with one of the grooves of the driving-pulley, while the opposite side of the tension-pulley is brought into alinement with the other groove in the driving-pulley. Further than this, the upwardly and downwardly moving portions of the driving-band are caused to pass between the oppositely-moving horizontal portions of such driving-band without bringing the crossing portions of the band in injurious chafing contact with each other. It may be also desirable to tilt the tension-pulley 9 to an angle from the vertical, as shown in Fig. 4, in which case the screw 13 may be loosened and a wedge 18 or piece of wood, metal, orother material inserted under one side of the bracket, as shown in said figure, such adjustment being useful for lining up the upwardly and downwardly moving portions of the drivingband with the grooves in the driving-pulley, while at the same time dodging the horizontally-moving portions of the driving-band. The manner of mounting the tension-pulley bracket, as shown in Figs. 2 and 3, also admits of the axial adjustment of the bracket and the additional adjustment of said bracket longitudinally of the bar 15 and in a direction parallel with the driving-shaft 2. By reeving the driving-band in the manner above described the spindles at opposite sides of the machine are simultaneously driven at equal speed, and by the arrangement of tension-pulleya uniform tension is given to the band at all times, and said band has the same driving engagement with both spindles. By reason of the fact that the driving-shaft is arranged above the spindle-rails and the tension-pulley located beneath the driving-pulley at very compact arrangement is obtained.

The ten sion-pulley, as stated, maybe adjusted to any desired angle or inclination, and when properly adjusted the adjustment may be fixed. The tension device is self-regulating and requires no attention after being primarily adjusted.

Instead of the construction employing the shaft 2 and separate drivingpulleys 7 a plain cylinder, as in Fig. 5, may be employed, extending the entire length of the machine, with or without grooves.

It is also within the scope of this invention to construct the pulleys 7 without grooves, although ordinarily the grooves are preferred, as they prevent the crossed portions of the band from chafing against each other.

Having thus described the invention, what is claimed as new, and desired to be secured by Letters Patent, is
